That's what I bought last Summer (Victron 75/15 MPPT) to replace the 3-4 various PWM Controllers I used in the past. (which chop off the available voltage at 12 volts like you said)
I think you will enjoy the monitoring system the Victron has plus it's increased efficiency. The only problem is that it tells you exactly how well your panels
are working so you may start doing what I did last year which was aiming my panels
for optimal performance (especially if you are not real busy while floating around)
I have one of my old PWM Controllers hooked up now though. Last Winter one of my PWM's failed due to condensation
from large temperature fluctuations.
We were at 22 degrees F this morning and will be at 60 degrees plus in a day or so. My boat
is in the yard now so I just have it set for like 13.2 volts float using just one 20 watt panel
The Victron will go back in this Spring (it's in my living room now sitting on my tackle box)
